I suggested only ''lightly moistened'' as you don't want any liquid to penetrate through to the internal components via any gaps next to the sensor window. Also to forestall and minimize any possible damage, do this with the laptop turned off. It would be preferable to also have the laptop battery disconnected as well but as long as you don't apply too much liquid it should be OK.
